A source has revealed on Weibo (via MacOtakara) that the iPhone 7 will be water- and dust-proof, and that Apple may ditch the metallic casing and switch to another material to make that possible. The torture tests the iPhone 6s was subjected to revealed that the latest devices will survive a short while underwater, but it’s better to avoid contact with water.

The Apple Watch, on the other hand, does have an official water resistance rating of IPX7, which means it is safe in water up to a meter deep for up to 30 minutes. That device could signal Apple’s possible move with the next-generation iPhone.

Furthermore, citing reliable sources, MacOtakara says the iPhone 7 will have a “completely flat” LCD screen. All the above should be taken with a grain of salt, since there is a whole year to go until the iPhone 7 launches, and Apple’s plans can change quickly.
